The Tyre Reviews Score is the most comprehensive tyre scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tyre tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

January 27, 2023

Hi, I am currently trying to decide between the Bridgestone Turanza ER300 215/60R16 or Michelin Primacy 4 205/60R16. Sellers have told me both fit in my Suzuki New Vitara, being 215/60R16 the actual manufacturers size reccomendation. But my question is which one should I go with? Is the size difference in this case detrimental? Or if not which is the better choice? Also I live in a tropical country so weather is usually hot and it rains pretty often. Roads are ok, but they can get somewhat flooded with heavy rains. Safety, comfort and logevity are my main concerns. Also other available options in my region are: Continental Premium Contact 2, Dunlop SP Sport lm705, Hankook Optimo H724, Bridgestone Ecopia ep150 and BFGoodrich Advantage. All of them in 215/60R16.

The ER300 is an older pattern now, so I would say the Primacy 4 is the better tyre. As for fitting a non-recommended size to the vehicle, that's not something I can advise on, however the difference in grip between the two sizes will likely be less than the difference in performance between the two tyres, ie a narrower better tyre will be better.

Review Summary

Based on 155 user reviews

Drivers largely rate the Bridgestone Turanza ER300 as a strong touring tyre with excellent longevity for many users, confident dry grip, and generally solid wet performance when newer. Many high-scoring reviews highlight long wear (30-80k miles), stable handling, and acceptable comfort/value, though road noise is a frequent complaint. A consistent minority report wet traction deteriorating as the tyre ages and some experience faster wear on specific vehicles, plus firmness/harsh ride on rough surfaces. Overall sentiment is positive, with the ER300 preferred by many over successors and rivals for dependable, long-wearing daily use.

Strengths
  • Long tread life
  • Good dry grip
  • Stable
  • Predictable handling
  • Decent wet grip when new
  • Value for money
Areas for Improvement
  • Noisy at motorway speeds/rough asphalt
  • Wet grip deteriorates with wear
  • Firm/harsh ride on rough roads
  • Inconsistent wear on some cars

Honda fitted the Turanza ER370 to the Jazz in 2019. This was a brand new car, lady driven extremely lightly, now only 17k km on the clock, and at least 2 tyres are warn and replaceable - biggest disgrace possible and never again a Brigestone tyre in my yard. I cant wait for the replacement. Chose Dunlop SP Sport 560 92H (found to be 6th best out of 146 tyre makes and versions compared) after most satisfied with Dunlop tyres on my ML Mercedes and new Fortuner.

The tires are awesome, best tire I’ve bought by far, they have lasted 60,000km and still have a lot of thread left, 3 and a half years using them, they handle great even in dirt.

Given 90% while driving a Honda (205/50 R16) on mostly country roads for 10,000 spirited miles
I have these tires for 3 years on my daily car.and on several other cars. I drive normally but sometimes hard or very hard. Beside regular driving i tried many times Top speed on autobahn for long distances when it was clear, touge, track . Anything you can think of except drifting because my car is not made to drift. I think they are by far the best you can get for the money as regular tires. Basically they are good for everything. They are not noisy, cheap compared with other premium tires, they last long. Good in the rain . Maybe the one weak point is they lost the traction starting from 4000 rpms after half of the life. But i have no TCS , ABS or any electronic help. My favorite thing is to drive hard on twisty mountain roads few times a year on these and i can do it without any cares. Even on tight twisty track they were just a second slower than R888R. Compared with other regular tires i think only Firehawk versions of sister company come close to these as cornering speed but Firestones were very bad on wet roads. I tried different types of Continental before, Dunlop Sp Sport, Hankook, Fulda and other things. Even Potenza Adrenalin Re002 or Re050 are significantly worst and dangerous at the limit compared with Er300. Another good thing is they are everywhere. Easy to find. I am not planning to change these tires for regular driving as long as i can find them .

Do a lot of miles and am always conscious of my tyres. I bought a new car that had these on it and they have performed well. Lots of motorways and spirited driving. Tyre has even wear and good on all aspects. In 100,000 miles I have only been through two sets!

First time with a Bridgestone tyre, came fitted to when new. Covered over 33,000 miles before having to replace the fronts at 2mm. One of the best tires I have driven, which is not a performance tyre, good dry grip and excellent wet grip with good feedback. Also good comfort for a 45 tyre. Should have replaced with the same and not chosen the T005, which is not as good.

Given 64% while driving a Ford Focus (215/50 R17) on a combination of roads for 9,000 average miles
Handling and Road Feedback are good with good braking and car control. In fact when the car is moving I like the tyre. My main problem is that starting from a stand state and going on inclined ramps I have a lot of wheel spin - even on dry surfaces. Not really on tarmac but on all kind of other surfaces. Thats the reason I won't buy them again and I'm disappointed with the brand and model of a premium tyre that shouldn't have this kind of problems. The comfort is not very good and the noise is a little high. Wear seems good.

Served me so well on good dry hot tarmaced road . They are so comfortable on the road with very low noise. Once it starts to wear the fuel consumption goes up better change them.
